Tire Test - Vittoria Open Corsa CX III Latex Tube

Test Summary

Compare up to 3 tires

This is part two of a latex vs butyl road bike inner tube comparison. I'm going to use last week's review of the Continental Grand Prix 4000S II with a latex tube Read Here as a template and won't add much to this review except the data. This time I'm using the Vittoria Open Corsa CX III reviewed
Here. Just like last weeks review I've substituted the standard 100 grams Continental butyl inner tube for a 80 grams Michelin AirComp A1 Latex tube.
I've chosen the GP4000S II and Open Corsa CX III to test a latex inner tube simply because these are the fastest road bike tires I had the chance to test up to now.

Use the formula: RR (watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load

The latex tube definitely has less rolling resistance when compared to the butyl tube, although the difference isn't as big as seen with mountain bike tires Read my special MTB article. Tests are run at 18 mph / 29 km/h, which might be a little low for road bikes.
